  • FUNCTION Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The reaction comprises two steps that are both catalyzed by the same enzyme: formation of S-adenosylmethionine (AdoMet) and triphosphate, and subsequent hydrolysis of the triphosphate.CATALYTIC ACTIVITY L-methionine + ATP + H2O = S-adenosyl-L-methionine + phosphate + diphosphateCOFACTOR Binds 2 divalent ions per subunit. The metal ions interact primarily with the substrate (By similarity). Can utilize magnesium, manganese or cobalt (in vitro) (By similarity).COFACTOR Binds 1 potassium ion per subunit. The potassium ion interacts primarily with the substrate (By similarity).PATHWAY Amino-acid biosynthesis; S-adenosyl-L-methionine biosynthesis; S-adenosyl-L-methionine from L-methionine: step 1/1.SUBUNIT Homotetramer.SUBCELLULAR LOCATION Belongs to the AdoMet synthase family.
